Though not the strongest grocery card, it is pretty strong.
If you value MRs, this is the best (US domestic) dining card.
The food credit is on the weak side if you don't hit grub hub on a regular basis already.
I think for most people (that value MRs) this is a really good improvement. It puts the PRG back on top of a lot of peoples wallets for a lot of transactions that generate valuable consumer data.
